Title: Liquid sealed type mount and assembling method thereof
Inventor: KINOSHITA SHINYA
IPC: B60K5/12
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To curtail the number of part items and make an assembling work easy by arranging the inner circumferential part of a diaphragm oppositely to an idle orifice through an inner circumference supporting ring fitted to the face on the opposite side to a liquid chamber on a partition wall. SOLUTION: In a diaphragm 7, when large displacement due to a shock is input to the main body part 7b surrounding a liquid chamber B on the outer circumferential side of a fitting part to the engaging step difference part 83 of an idle orifice D through an inner circumference supporting ring 72, sealed liquid L moves through a shock orifice C. Meanwhile, the inner circumferential part 7c facing to a liquid chamber A through the orifice D allows liquid column resonance at inputting vibration of small amplitude due to idling. Apart from a main body vulcanized molding constituted of an outer cylinder 1, a center boss 4, and an elastic body, three members, namely, a partition wall 8, the diaphragm 7, and a cup member 2 are temporarily assembled, and after excluding air from the respective inner spaces in a liquid tank, the sealed liquid L is enclosed and both are combined together.  Hereby, a caulking work outside the tank is facilitated, and hence air extraction and liquid charge can be surely performed.

Title: Liquid crystal display device
Inventor: HIOKI TAKESHI
IPC: G02F1/135
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To give gradation display without being limited by the threshold characteristics of liquid crystal material by providing a ferroelectric film having a first and a second domain polarized in different directions and a domain moving means which moves its boundary by impresssing an electric field. SOLUTION: The voltage impressed on a pixel electrode 2 is divided and impressed on a liquid crystal layer 6 by a first domain and a second domain of the ferroelectric thin film. The electric field impressed on a pixel region formed by the pixel electrode 2 and the counter electrode 5 is modulated by the ferroelectric thin film 1 to conduct gradation display. Since the ferroelectric crystal is composed of domains different in polarization, the liquid crystal layer 6 is divided into pixel domains which correspond to the domains of the ferroelectric crystal and its orientational conditions and phase transition conditions are controlled. For example, the ferroelectric thin film 1 is formed by a ferroelectric body having a polarization axis parallel to the normal direction of the substrate.  It is effective that the polarization axis and the normal direction of the substrate are close to parallel.
